Lots of good stuff here, but it's mostly personal feelings about various substances. What the hell, I'll add to the drivel.
I'm 64 3/4 years old. Started drinkin', druggin', and smokin' when I was 14. I was in a man's world at the time and I did what the men around me were doing and I didn't give a fuck what anyone thought. I was also 10' tall and bullet proof then, just like most 14 year olds are. And I did it all then the way I wanted to. I thought I was a tough kid so I smoked straight Camels or Pall Malls like my dad, drank whiskey out of the bottle, and beer that was sunk in the cow tank which meant is was only less warm than fresh piss. I was growing very potent as a teenager that would knock any man's dick in the dirt. I tried and frequently used every drug known to man that it was possible to use in a profane manner. It was the world I lived in. Part of me still lives in that world. I don't know jack shit about flavors because I don't use them. I mix my own juice and I take it straight w/ vg.
My weakness was ANYTHING that would make me feel good, or I THOUGHT would make me feel good, I became totally addicted to. Some of it caught up with me fairly quickly. I sobered up at 26 and I have been clean and sober for 38 years. With tobacco, I swapped out the Camels and Pall Malls for filtered cowboy killers (Marlboros) when I was 34 or 35. My smoke of choice for the last 10 years of smoking was American Spirits. I finely gave up the smokes at age 61 when my health collapsed. But I'm a true addict, so to stay off the smokes, I started vaping. Problem solved and it may have been the only way I could pull off not smoking. I vape 10 mg nic in all vg because pg makes my throat itch.
The whole point of this confession is that all the stuff I did, I did it because I thought it was cool, or made me feel alive on some cutting edge, or made me an equal of my peers, or was looked down on by many people, frightened the hell out of a lot of others, or I liked the danger, or just plain made me feel good. Most of all, I liked the image of being a rebel. In the moment there was no down side. Girls liked tough guys who looked good and smoked, drank, and did drugs. Well, at least some did.
Now, I don't know what is going to rope a kid in these days. I suspect it's the same old things with maybe a few new ones thrown in. Availability of flavored juice is academic - if some kid finds it seductive, they will get their hands on it. An attractive nuisance you might say - I know a guy who built a swimming pool out back but ended up filling it in because he couldn't keep the local kids out of it in the middle of the night.
So I don't think trying to control it will have any effect; only make it more attractive. As for gateways; anything is a gateway to someone like me. I think I was addicted to nicotine long before my first cigarette from having a chain smoking dad in the house.
Also, I dislike laws that restricts the free movement of people or goods. Restrictive laws have made many criminals out of honest regular folks. But hell, I would let anyone have machine guns. That's just me.
The one thing I do advise to everyone. Don't ever get too sanctimonious or judgmental about these issues. Is vaping safe and/or good for you? I think it IS safer and it does LESS harm than smoking, but I don't buy for a minute that it is perfectly safe. It has been my personal experience that anything and everything I like to do is gonna end up being bad for me. For every person beating on the table and railing about the injustice of it all, remember there is someone else who is equally convinced that vaping is an instrument of the devil and should be banned - just like they have tried to ban alcohol and drugs at various times. And we know how THAT has worked out...
